18702 Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta washer is a load-distributing and spacing component manufactured to the specified diameter, thickness and material used in the steering mechanism and belt-tensioner/fan-pulley assembly. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it controls spacing and distributes load at the steering pivot or accessory-drive fastener. Selection must be confirmed by OEM part number 18702, the exact engine or product model, serial number and installed configuration.

🔌 Function

Controls spacing and distributes load at the steering pivot or accessory-drive fastener. Fit in the original orientation beneath the correct fastener and inspect the mating surfaces for wear or fretting.

⚠️ Common Signs of Failure

• Permanent cupping, cracking or distortion
• Fretting, polished movement marks or elongation around the hole
• Loss of clamp load or loosening of the associated fastener
• Incorrect spacing or misalignment of the retained component
• Corrosion or surface damage reducing effective support area

🛠️ Service Notes

• Check you are fitting the same type of washer that came out — plain, hardened, sealing and locking washers are not interchangeable, and the wrong one either fails to seal or fails to hold
• Treat sealing washers on fuel, oil and coolant unions as single-use; they seal by deforming onto the faces, so a used one will not seal reliably a second time
• Clean the seating faces and make sure the washer sits flat and square, fully under the head or nut, before tightening — a washer trapped on a chamfer or edge will crush unevenly
• Tighten the fastener to the figure given in the workshop manual for your engine, and account for every washer on reassembly so none is left loose inside a housing or the engine bay
